If so you can use the OGR driver (built it with INPUT_PLUGINS=all) to create and render the GML file directly. http://trac.mapnik.org/wiki/OGR The OGR plugin is very similar to the other Mapnik datasource plugins except that you need to supply the <layer> parameter. The name of OGR Layers can be found by running the 'ogrinfo' tool on your GML file like: $ ogrinfo <your_file.gml> -s0 -al > > I read that rendering maps follow the painter's algorithm.
